CARRIAGE-AXLE LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 350,780, dated October12, 1886.

A pplieation filed April 26, 1586. Serial No. 200,193. (No model.)

To all whom it may concern:

Be it known that I, Josnra SLADDIX, of Lawrence, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Carriage-Axle Lubricators, of which the following, takenin connection with the accompanying drawings, is a specification.

My invention relates to the lubrication of carriage-axles; and itconsists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to thedescription of the drawings, and to the claims to be hereinafter given.

Figure l of the drawings is a side elevation of the central. portion ofa carriage wheel mounted upon its axle and having my invention appliedthereto. Fig. 2 is a transverse section through two of the spokes of thewheel, and showing the lubricator in plan. Fig. 3 is a vertical sectionthrough the centers of the spokes in a plane at right angles to the axisof revolution of the'wheel; and Fig. 4 is a vertical section through thelubricator audits casing on line :0 :0 on Fig. 3, but showing aslightly-modified construction of the oilronduit.

In the drawings, A is the hub, and B B the, spokes, of a carriage-wheelmounted upon the axle C, and secured thereon by the nut- D, in awell-known manner, the outer portions of the spokes, the felly, and tirebeing broken away as unnecessary to the proper understanding of myinvention.

E is a metallic casing fitted to the angular space between two spokes,near the hub, its edges being curved to fit the sides of said spokes,and said easing being of an exterior width not greater than thethickness of said spokes in the direction of the length of the hub ofthe wheel, as shown in Fig. 2. The casing E is provided at its smallerend with the tu bular stem (1, which is fitted to a radial hole in thehub A, and between two of the spokes B, as shown in Fig. 3. The casing Eis formed with its outer or larger end open, with its two broader sidesextending above the two narrower sides, which fit against the spokes,and said opening is closed after the oil-cup F is placed in position bythe cap or bar b, fitted between the higher side plates, and securedthereto by the bolt 0, and to the spokesby the screws (1 d, as shown inFigs. 1 and 8.

Gis the oil-cup, made with two parallel sides and two sides that are atan angle to each other, corresponding substantially to the angle of thetwo spokes between which it is placed, and is provided at its smallerend with the tubular stem 6, which fits loosely the inte rior of thestem u of the casing, and extends to and rests upon the axle O, as shownin Fi 3. The oil-cup G is provided in its other end with an opening forintroducing the oil, which opening is closed by the screw-plug f,provided upon its outer surface with a pintle, f, to receive the springg,interposed between said screw-plug and the cap or bar I), which springis made of sufficient tension to maintain the end of the stem e incontact with the axle as the wheel revolves around the same.

The oil-passage through the stem 0 may be made of snfficient size toreceive the packing of absorbent material 71, as shown in Fig. 3, or itmay be contracted at its discharge end to amere pin-hole, and thepacking may then be dispensed with, as shown in Fig. i, the object to beattained being to deliver to the axle only so much oil as may benecessary for the proper lubrication of the axle.

The casing E may be dispensed with, if desired, retaining the stem (1 asa bushing to guide the stem 0 of the oil-cup, and the bar I) totake thethrust of the spring ,without affecting the operation of the lubricationof the axle; but I prefer to use the casing as shown as a protection forthe oil-cup.

In another applieation of even date herewith l have shown and describedan oil-cup for use on general machinery, which ope-rates upon the sameprinciple as the one here shown and described, and therefore in thisapplication I do not claim, broadly, an oil-cup having the end of itsdischarge-stem resting upon the shaft to be lubricated and movable toand from said shaft.

\Vhat I claim as new, and desire to secure by Letters Patent of theUnited States, is

1.. In combination with a carriage-wheel and its axle, an oil-cuplocated between two of the spokes of said wheel, and provided with atuin the hub, an oil-cup within said casing and provided with a tubulardischarge-stem fitted to a bearing in the hub of the casing, with itsend resting upon the periphery of the axle, a bar connecting said spokesand closing the outer end of said: casing, and a spring interposedbetween said bar and the oil-cup.

In testimony whereof I have. signed my name to this specification, inthe presence of two subscribing witnesses, on this 24th day of April, A.D. 1886.

JOSEPH SLADDIN.
